Windows update version 20h2 is stuck at 20% installing

Hi WongLi.

My name is Daniela, I am an independent advisor.

I hope you are very well.

Try restarting or stopping the Windows Update Service. To do this, follow the instructions below:

Go to Control Panel.

Click the left mouse button on the search box displayed in the Control Panel window.

Type in the search box: Administrative tools.

Click with the left mouse button or click on the Administrative Tools function.

Now double-click on the Services function.

You may be asked for an administrator account and password, in this case you will need to enter them.

In the displayed list you should look for Windows Update.

Right-click on the Windows Update service. From the menu that appears, click Stop. You can also select the Restart option.

Finally, restart your computer.

Go back to the Windows Update Service, left-click on it and select Start.

Have a wonderful day.

Best regards.

Daniela.

I have the same issue. It's been stuck at 20% for 4 hours. The solution posted doesn't work when you can't get past the "Working on updates 20%" screen. I'm on the verge of powering it off and taking my chances. It did this 2 days ago when attempting to install it and took 9 hours before it timed out. Ridiculous.

I've tried to install this update on my laptop, but it's stuck at 20% installing. Any help?

I have the same issue with 2021-02 Cumlative update for windows 10 version 1909 for x64 based systems ( KB5001028 ) stopping at 20%.

Hi Daniela

I have the same issue with this update. I followed your advice but I cannot click on the 'Stop' as all options are greyed out.

Help please

I have the same problem with x64 at 19% running for the last 6 hours. I don’t want to power down/restart as the last time I did this during an update caused lockout, hassle, time and money for an engineer to get the laptop up and running again. Can someone offer advice on what to do to resolve the issue during blue screen ‘working on install’ please?
